Overdrive vs Ring & Pinion

[hgs_notes]

I was thinking the other day, yeah it hurt, that just changing the ring and pinion so the final drive ratio would be the same as if you kept the original gears but installed an OD tranny would be a pretty cheap and easy way to save fuel. I know you would lose the low end power and this is not a fix all thing, but for the many people here that are using the truck as a driver it should work.

If you have a 4 speed manual tranny now, the effect would be similar as having an OD automatic. The 3 speed would pull a bit slower to speed maybe. You can get as low as a 2.56 or 2.73 ring and pinion set I think for our axles. If you had 3.73's originally that would be .73 OD for the 2.73 gears and .68 OD using the 2.56 gears.

I'm done thinking now. Go about your business.
